The IWG-EMC 52nd meeting is scheduled for 7 May 2026 as a web conference. The agenda includes feedback from the GRE 94th session regarding Supplement 3 to UN R10.07 and discussion of the roadmap for 08 series of amendments with proposals from Contracting Parties and non-governmental organizations. The session will address GRE-94-56-Rev.2 and documents covering topics such as harmonics limits, charging conditions, immunity requirements, and radiated requirements. The next meeting is scheduled for 1–2 July 2026 in Paris.

Proposal to address REESS using offboard AC/DC chargers. Some vehicles with REESS use offboard AC/DC chargers, a configuration not described in UN R10. The proposal adds test configurations for vehicles charging through offboard AC/DC chargers to multiple annexes, including flowcharts defining charging mode configurations and specifications for AMN or DC-charging-AN or AN for offboard AC/DC chargers below 60 Vdc. The proposal is based on IWG-EMC-49-12e.

Proposal to update Terms of Reference for the Informal Working Group on Electromagnetic Compatibility. Items 21 and 22 add timelines for the 08 series of amendments of UN Regulation No. 10: an informal document for the 95th session of GRE in October 2026, and a formal document for the 96th session in April 2027, with final submission by end of January 2027, for adoption in WP.29 in November 2028.

OICA opposes inclusion of four roadmap items in UN R10.08 amendments based on WP.29 principles for evidence-based rulemaking. Items 2 and 2bis (radiated emissions below 30 MHz) fail reproducibility standards, lack validated test methods for all vehicle categories, and rely on standards not applicable to internal combustion engine vehicles. Item 3 (16 GHz range) violates the requirement for specific standard versions as CISPR 12 lacks finalized methodology. Item 4 (variable driving conditions and 4-side antenna assessment) presents measurement reproducibility concerns. OICA recommends deferral pending publication of validated international standards.

Proposal to add radiated emission testing requirements in the frequency range 1 GHz to 6 GHz. New clause 6.2.2.5 specifies limits for vehicle measurements at 3.0 ± 0.05 m antenna distance using peak and average detectors, with limits of 70/50 dB(V/m) for 1000–3000 MHz and 74/54 dB(V/m) for 3000–6000 MHz. New Annex XY describes test methods using IEC 61000-6-3 Ed.4.0 and CISPR 12 provisions. New clause 6.5.3 establishes ESA broadband type approval limits with higher thresholds. New Annex XZ prescribes ESA measurement methods, including test arrangements for REESS charging mode coupled to the power grid.

Proposal to establish items for the 08 series of UN R10: address immunity-related functions required by multiple UN Regulations through discussion of whether to include these features in UN R10 or relocate electromagnetic compatibility provisions to individual UN Regulations; amend test procedures for complex systems including steer-by-wire, brake-by-wire, and ADAS features to establish clear protocols and reduce unlevel playing field items; improve the general approval process through precise vehicle type description and definition of high-level objectives; describe dwell time selection through ISO standard 1154 as minimum; discuss ISO 17025 evaluation principles; discuss antenna position at 3m versus 10m for best-case and worst-case scenarios; and require robust electromagnetic compatibility protection with critical details described in test reports and information documents.

OICA proposes that Roadmap Items 2, 2bis, 3, and 4 be withdrawn or deferred until relevant international standardization bodies publish validated methodologies. OICA opposes radiated emissions requirements below 30 MHz in driving and charging modes, radiated emissions in the 16 GHz range, and variable driving conditions assessments, citing lack of technical rationale, absence of published international standards, poor reproducibility for large vehicle categories M₃ and N₃, and inconsistency with WP.29/2024/39 reproducibility standards. New R10.08 work items must demonstrably enhance safety, align with published international standards, and maintain regulatory stability per ECE/TRANS/WP.29/1044/Rev.3 and WP.29-196-07, WP.29-196-26, and ECE/TRANS/WP.29/1182.

Proposal to insert new paragraphs 0 through 0.1.2, amend paragraphs 1.1, 1.3, and 2.12, insert new paragraphs 2.9.4 and 2.32, delete paragraphs 2.26 and 2.27, insert new paragraph 3.1.9, insert new paragraph 6.11 with sub-paragraphs, amend paragraph 9.3.2, and amend Figures 3, 4, 5, and 6 in Appendix 8, and add items 74 and 75 to Annex 2A, insert paragraph 7 in Annex 3A, and amend Annex 4, Annex 5, Annex 6, and related sections to accommodate ADS vehicles, including categories X and Y.
